To all rwhomt't may concern.'

y Be it known that I, FRANK H; CRUMP, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a certain new and useful Im rovementin Posting-w osts, of which the ollowing is a speciiicatlon. Mymvention is an improvement in posting posts, and consists in certain novel conledger provided with` theyf'improved post. Fig. 2 is a side view of the posting post and the extension bolts partly in section, and

Fi 3 1s aside view of the post.

he'posting post proper comprises an.

arched member, having a body portion A o and limbs or arms B and C, the arm B having a reduced portion D, and the arm C a threaded recess E in the end thereof. The arm B is also provided withl a shoulder F between the reduced ortion and the arm roper against which t e end of the binder bolt bears as shown in Fi 2. The binder bolt may ge of any suitable construction, that shown consisting of inner sections G, extension members H, sleeves I` and outer sections'K 'and' K. The inner members or sections G comprise each, ahead 'p40 L, rovided with a korf, for the insertionof 'atoo to -turn the section, a threaded portion 'N,. for engagement by the threaded portion N of. the sleeve I, and a reduced threaded portion O, for engagement by the extension member I-I; vThe sleeves I lare internally threaded at one end, and are beveled at the otherso as to revent thev catching of the sheets thereagalnst, and fit over the extension members H as shown in Fig. 2, and the end of thesleeve yabut's against a shoulder Q formed on. the inner member between thev head and the portion N. The extension members H consist each of a tube closed at one end ,and internally threaded for engaging the threaded portion O of the inner mem er,

hereof. Figure 1 is a perspective view of a y and the closed end is provided vdth a reduced screw threaded lug or portion R for engagin another extension member or the threads reeess screw of the posting post, as the case may be. The outer'seotlon K is an open ended tube, internally threaded for engaging the lug R on the other portion of the inner section, and the other end is adapted to re.

ceive ,the reduced 'portion D of the arm B of the osting post. The outer section K is simi ar in all respects to the extension members H, and the threaded, lug thereon enga es the vthreaded recess E in the arm C.

n operation,-the top cover of the binder is removed and laid flat, with the binding edge close to the binding edge oi the bottom cover. The posting posts are new inserted and secured 1n place, after which the leaves ma be turned over the body portion of the are the leaves however always lying flat on'- each side.

In Fig. 2 ins T are shown, traversing the arm C and tli are used to ltighten the posts.

The improvement as a whole may be considered as consisting of a yoke, comprising a body ortion and sectional arms, the body portion eing detachably connected with one arm, and rotatably connected with the other. I claim- In a loose leaf binder, extension binder posts, each of said osts comprising inner and outer sections, t e inner sections bein Iexternally screw threaded and'provided wit l`a'lsleeve, the Aouter sections being internally screw threaded and fitting Within the sleeve when the inner section 1s screwed thereinto, one of said outer sections having its freeend e adjacent outer section, which Aopenand the other having its free end closed and provided with a reduced screw threaded ort'ion, an arch member one arm of which is etachably coni'eeted-with-the iirst named outer section and the other arm of which is provided with a screw threaded o ening for receiving the reduced extension o the other outer section, and extension members internally screw threaded for receiving the inner section and Vhaving reduced screw threaded portions for screwing into the outer section and adapted to be inserted in between said inner and outer sections.
